I have collected stamps and not financial investments in stamps. So the quality is according to my budget. My expectations regarding your offer will have this aspect in mind too.
I have created an own systematic. If you like you can get the Powerpoint and Excels too to adjust and reprint.
Collection of about 1300 stamps, sorted by Type, Die, Flaw, Position, lot of higher values, units and mint items
The shown images are just to get an idea. For the whole collection I needed about 5o scans
two SPECIMEN, unused
high catalogue value
Collection of Commonwealth issues from 1903. Both types
Some with original gum
There is one stamp with a flaw „S“ in QUEENSLAND and some gum on the front side too (darker vertical stripe in middle and top left corner)
